BPSK (Binary Phase Shift Keying)，把模拟信号转换成数据值的转换方式之一，利用偏离相位的复数波浪组合来表现信息键控移相方式。BPSK使用了基准的正弦波和相位反转的波浪，使一方为0，另一方为1，从而可以同时传送接受2值(1比特)的信息。-BPSK，The conversion of analog signals into data values is one of the ways of converting the analog signals to the complex wave of the phase of the signal. BPSK uses a reference of the sine wave and the phase inversion of the wave, so that one side is 0, the other is 1, which can simultaneously transmit 2 values (1 bits) of information.
